Rann-Thanagar War Question

So, Rann-Thanagar War is the only Infinite Crisis mini on which I decided to pass, but now that the event is almost here, I'm worried I've missed something. The reason I decided not to buy it was because I assumed it would be tied into the Adam Strange mini that ended almost right before it started. For anyone who's read both, is there anything in the Adam Strange mini that has a bearing on RTW? If it's relatively minor, feel free to just spill it. I'd like to try and catch up on Rann-Thanagar and want to make sure I'm not missing anything.

Rann-Thanagar War is a direct sequel to the (far superior) Adam Strange mini.

This is also the reason why it's not so good. If you haven't read the miniseries, and aren't up on continuity, Rann-Thanagar is a train wreck. Pretty much all the necessary setup that should be in Rann-Thanagar is done in the Adam Strange mini, and what's left isn't enough for 6 issues (IMHO)

The Adam Strange mini has already been collected into a TP called Planet Heist. If you've got the $20, you should get it.

Rann-Thanagar is far and away the worst of the Countdown minis. The story's not as nearly as fun as Villains United or Day of Vengeance, and honestly seems really crowded. Maybe it's just because I'm new to DC and don't know much about it's outer space places and characters. Still, I don't know anything about its magic world, and Days of Vengeance reads just fine.

I'm actually enjoying Rann-Thanagar War, but as XCN said, it's due mostly to my reading the Adam Strange mini and having a good amount of knowledge in the backstory about many of the characters. While it isn't as good as OMAC or Villains United, I still feel it ranks above Day of Vengance.
